A visitor visa application is a credibility exercise. The officer must be satisfied that you will leave Canada at the end of your authorised stay.
Purpose of visit
Be specific. “Tourism” with no itinerary, no bookings and no explanation is weaker than a clear plan tied to your circumstances.
Funds
Show that you can pay for the trip without working in Canada. Bank statements should have a history that matches your stated income.
Ties
Employment, property, dependants and community responsibilities all matter. So does a realistic reason to return.
The super visa
For parents and grandparents of Canadian citizens and permanent residents, the super visa allows longer visits and requires private medical insurance meeting the published conditions, plus a host who meets the income requirement.
